The Anasuria Cluster, located approximately 175km east of Aberdeen in the Central North Sea, United Kingdom, incorporates the Teal, Teal South, Guillemot A and Cook fields, all of which share the Anasuria floating production, storage and offloading (FPSO) host platform.
The cluster of oil and gas fields is owned and operated by Anasuria Operating Company (AOC), a 50:50 joint venture (JV) between Hibiscus and Ping Petroleum. The JV acquired the project from Shell UK, Shell EP Offshore Ventures, and Esso Exploration and Production UK (ESSO) in March 2016.
The JV has a 100% ownership in the Teal, Teal South, Guillemot A fields, as well as the Anasuria FPSO, and a 38.65% in the Cook field. The remaining 65.35% share in the Cook field is held by Ithaca Energy.
Field Commissioning and First Production from the cluster had commenced in 1996 following the installation of the FPSO that year. The water depth within the project site is approximately 94m.
The Anasuria FPSO is installed within Block 21/25, between the Teal and Teal South fields. It is fixed to the seabed, at a water depth of approximately 89m, by a turret mooring system, and was Shell’s first purpose-built FPSO facility to be installed in the North Sea.
The primary separation and processing facilities of the FPSO include two first stage separators, a second stage and third stage separator each, two HP water injection pumps, and seven oil cargo tanks with a storage capacity of 20,000 million standard cubic metre (mmscm) each. It further incorporates three gas compressors and the platform has a designed processing capacity of 11,000m³/d.
The vessel weighs 125,000t and is equipped with a main control room, a switchgear module, and a helideck.
